DETAILED DESCRIPTION

In order to make the technical problems to be solved, the technical solutions and the advantages of the embodiments of the present disclosure clearer, a detailed description will be given below with reference with the drawings and specific embodiments.
Fig. 1 is a schematic view showing a network structure to which embodiments of the present disclosure may be applied. As shown in Fig. 1, the network structure includes a terminal 11 and a network-side device 12. The terminal 11 may be user equipment (UE) or other terminal devices, for example, a terminal side device such as a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a mobile Internet device (MID), a wearable device, a robot, or a vehicle. It should be noted that a specific type of the terminal is not limited in the embodiments of present disclosure. The network side device 12 may be an access network device, for example, a base station such as a macro station, a long term evolution (LTE) base station (evolved Node base station, eNB), a fifth generation (5G) new radio (NR) base station (gNB), etc. The network side device may also be a small station, such as a low power node (LPN), a pico, a femto, or the network-side device may be an access point (AP). The network-side device may also be a central unit (CU). The above-mentioned network-side device may also be a core network device, such as a mobility management entity (MME), an access management function (AMF), a session management function (SMF), a user plane function (UPF), a serving gateway (SGW), a public data network gateway (PDN gateway), a policy control function (PCF), a policy and charging rules function (PCRF), a serving general packet radio service (GPRS) support node (SGSN). It should be noted that a specific type of the network side device is not limited in the embodiments of present disclosure.
Fig. 2 is a flow chart of a scheduling method according to an embodiment of the present disclosure. As shown in Fig. 2, the scheduling method includes the following step 201.
Step 201, receiving, by a terminal, DCI sent by a network-side device, where the DCI is used for scheduling transmission of N channels or N signals of the terminal. The N channels include N uplink channels or N downlink channels, the N signals include N uplink signals or N downlink signals, where N is an integer greater than 1.
The N channels may be N channels on a same carrier, so it is possible to schedule the transmission of multiple channels on one carrier through one DCI. Alternatively, the N channels may be channels on different carriers, so it is possible to schedule the transmission of channels on multiple carriers through one DCI. For example, the N channels are N channels on N carriers respectively, in this way, the transmission of one channel on each carrier is scheduled through the above-mentioned DCI. Of course, it is also possible to schedule the transmission of one channel on one carrier, and to schedule the transmission of multiple channels on one or more carriers.
The N signals may be N signals on a same carrier, so it is possible to schedule the transmission of multiple signals on one carrier through one DCI. Alternatively, the N signals are signals on different carriers, so it is possible to schedule the transmission of signals on multiple carriers through one DCI.
In addition, the transmission of the N channels or N signals may be sending or reception of the N channels or N signals.
In the embodiment of the present disclosure, through the above steps, it is possible to schedule the transmission of multiple channels or multiple signals through one DCI, thereby improving the scheduling efficiency of the DCI as well as improving the scheduling flexibility.
In an optional implementation, a bit length of at least one information field in the DCI corresponds to a configuration parameter.
The at least one information field may be the entire information of the DCI, i.e., bit lengths of all information fields of the DCI correspond to the configuration parameter. Alternatively, the at least one information field may be some information fields of the information fields in the DCI, i.e., bit lengths of some information fields in the DCI correspond to the configuration parameter.
In addition, the configuration parameter may be a configuration parameter configured by a network side, such as a high-layer configuration parameter. Of course, the configuration parameter may also be a configuration parameter predetermined in a protocol. The configuration parameter may be a configuration parameter related to scheduling of channel or signal transmission, such as a time-domain resource allocation (TDRA) table, carrier bandwidth information, and a subcarrier spacing.
That the bit length of at least one information field in the DCI corresponds to the configuration parameter may be understood as that the bit length of the at least one information field in the DCI is determined by the configuration parameter. In addition, that the bit length of an information field corresponds to the configuration parameter may mean that the bit length of the information field may effectively indicate the scheduling of multiple channels or multiple signals in accordance with the configuration parameter.
In the implementation, the bit length of the at least one information field in the DCI corresponds to the configuration parameter, so it is possible to determine the length of the information field effectively, thereby reducing DCI overhead and avoiding introduction of an excessive DCI payload size.
In an optional implementation, the at least one information field includes a first information field, and a bit length of the first information field is a maximum length of the first information field that corresponds to one or more sets of configuration parameters.
The maximum length of the first information field that corresponds to one or more sets of configuration parameters may be a maximum length of the first information field determined by the one or more sets of configuration parameters, and the maximum length may indicate the scheduling of the channels or signals in accordance with each set of configuration parameters among the one or more sets of configuration parameters
In the implementation, the bit length of the first information field is the maximum length, in this way, the scheduling in accordance with each configuration parameter may be effectively indicated.
Optionally, the first information field includes an information field for TDRA, and the one or more sets of configuration parameters include one or more TDRA tables.
The TDRA table may be configured at the network side and transmitted to the terminal, for example, a TDRA table configured through RRC signaling; or the TDRA table may be determined in a protocol.
In this way, a bit length of the information field for TDRA may be determined through the TDRA table.
Optionally, the one or more TDRA tables are N TDRA tables, and different TDRA tables correspond to different respective channels or signals. The N TDRA tables have a same quantity of rows, and a bit length of the information field for TDRA corresponds to the quantity of rows of the N TDRA tables. Or, the N TDRA tables have different quantities of rows, and the bit length of the information field for TDRA corresponds to a maximum quantity of rows among the N TDRA tables. Or, the bit length of the information field for TDRA corresponds to a total quantity of rows of the N TDRA tables.
That different TDRA tables correspond to different respective channels or signals may mean that different TDRA tables correspond to different respective carriers, i.e., N different carriers scheduled by one DCI are configured with N TDRA tables independent from each other, specifically, the DCI schedules N channels or N signals on different carriers. Optionally, that different TDRA tables correspond to different respective channels or signals may mean that different TDRA tables correspond to different channels or channels on the same carrier
That the N TDRA tables have different quantities of rows may mean that different TDRA tables have different quantities of rows, or, some of the TDRA tables have a same quantity of rows and the rest of the TDRA tables have different quantities of rows.
The quantity of rows of the TDRA table may be a quantity of rows including TDRA information, and exclude the first row of directory information of the TDRA table. Of course, the quantity of rows of the TDRA table may also be the quantity of all rows, i.e., including the first row of directory information of the TDRA table. In this way, when determining a correspondence between the bit length and the quantity of rows of the TDRA table, the first row needs to be removed.
That the bit length of the information field for TDRA corresponds to the quantity of rows of the TDRA table may mean that the information field may indicate all entry indexes in the TDRA table.
For example, in a case where N TDRA tables have the same quantity of rows, a TDRA indication field in the DCI is determined by the quantity of rows of the TDRA tables, and every status bit indicates the entry index in the TDRA table. For example, assuming that the TDRA tables each have 16 rows, then 0000 indicates a first row of the TDRA table (it should be noted that the first row does not refer to a first row of the entire table, but refers to a first row of the TDRA table that includes time domain resource allocation information, such as a row where a table index is 0), so that the terminal sends and receives data on a component carrier (CC) #1 in accordance with a first row of a table corresponding to the CC#1, sends and receives data on a CC#2 in accordance with a first row of a table corresponding to the CC#2, and so on.
Optionally, in case that the bit length of the information field for TDRA corresponds to the maximum quantity of rows among the N TDRA tables, all bits of the information field for TDRA are used to indicate an entry index in a first TDRA table, and M1 least significant bits (LSBs) of the information field for TDRA are used to indicate an entry index in a second TDRA table, where the first TDRA table is a table having a maximum quantity of rows among the N TDRA tables, the second TDRA table is a table having a quantity of rows different from the first TDRA table among the N TDRA tables, where M1 is an integer greater than or equal to 1.
M1 may correspond to the quantity of rows of the second TDRA table.
In this way, it is possible to save the overhead of the information field effectively.
For example, in a case where the N TDRA tables have different quantities of rows, the TDRA indication field in the DCI is determined by the maximum quantity of rows in the configuration tables, and each state indicates an entry index in the TDRA tables. For example, if N=2, a TDRA table configured for CC#1 has 32 rows, and a TDRA table configured for CC#2 has 16 rows, then the TDRA indication field in the scheduling DCI has 5 bits. For a corresponding carrier, the terminal determines the time domain resource allocation information on the carrier according to M1 LSB bits determined by a TDRA table of the carrier. For example, for state information 11111, the terminal sends and receives data on CC#1 in accordance with the 32^nd row in the corresponding TDRA table, and sends and receives data on CC#2 in accordance with the 16^th row in the corresponding TDRA table
Optionally, in case that the bit length of the information field for TDRA corresponds to the total quantity of rows of the N TDRA tables, the information field for TDRA includes N bit parts, where the N bit parts are used for indicating entry indexes in the N TDRA tables respectively.
The above N bit parts may be ordered according to the N TDRA tables, so as to sequentially indicate the entry indexes in the N TDRA tables.
For example, the length of the information field is determined by the total quantity of bits of the N TDRA tables, every Xi bits in the information field is used for indicating TDRA on the i^th CC among N CCs, and Xi bits of different CCs do not overlap with each other, Xi is a value determined in accordance with a size of a TDRA table of the i^th CC. For example, if N=2, the TDRA table configured for the CC#1 has 32 rows, and the TDRA table configured for the CC#2 has 16 rows, then the length of the TDRA information field is log2(32)+log2(16)=9 bits, where 5 most significant bits (MSBs) are used for indicating the time domain resource allocation on the CC#1, and 4 LSBs are used for indicating the time domain resource allocation on the CC#2.
Optionally, the one or more TDRA tables are a common TDRA table including TDRA information of the N channels or N signals, and a bit length of the information field for TDRA corresponds to a quantity of rows of the common TDRA table.
That the common TDRA table includes the TDRA information of the N channels or N signals may mean that the common TDRA table includes the TDRA information of the N carriers, since the N channels or N signals may be channels or signals on the N carriers.

Different CCs may be configured with the same common TDRA table, e.g., all the N carriers are configured with the common TDRA table. The common TDRA table is as shown in Table 1.

Table 1

TDRA table index	TDRA for CC#1	TDRA for CC#2
0	combination 1 of a Mapping type, K0/K2, S, L and R	combination	1 of a Mapping type, K0/K2, S, L and R
1	combination 2 of a Mapping type, K0/K2, S, L and R	combination	2 of a Mapping type, K0/K2, S, L and R
2	combination 3 of a Mapping type, K0/K2, S, L and R	combination 3 of a Mapping type, K0/K2, S, L and R
3	combination 4 of a Mapping type, K0/K2, S, L and R	combination 4 of a Mapping type, K0/K2, S, L and R
4	combination 5 of a Mapping type, K0/K2, S, L and R	combination 5 of a Mapping type, K0/K2, S, L and R
5	combination 6 of a Mapping type, K0/K2, S, L and R	combination 6 of a mapping type, K0/K2, S, L and R
6	combination 7 of a Mapping type, K0/K2, S, L and R	Null
7	combination 1 of a Mapping type, K0/K2, S, L and R	Null
...

In this way, it is possible to indicate the scheduling on the carrier through one table, and save the overhead of DCI. It should be appreciated that, Table 1 is merely for an illustrative purpose. The aforementioned common TDRA table may also correspond to the time domain resource allocation of three or more carriers.
In an optional implementation, it is not expected by the terminal that transmission start positions of the N channels or the N signals are before a reception time of the DCI.
In the implementation, it may be achieved that the terminal side does not expect that a starting position of data transmission is prior to the reception time of the corresponding scheduling DCI, and even if it is prior to the DCI reception time, the terminal may determine that the channel or signal is erroneous and do not perform transmission.
In an optional implementation, the first information field includes an information field for frequency domain resource allocation (FDRA), and the one or more sets of configuration parameters include one or more pieces of BWP information.
The BWP information may include such information as bandwidth information, resource block (RB) information, and a subcarrier spacing. The BWP information may be configured at the network side and transmitted to the terminal, for example, BWP information configured through radio resource control (RRC) signaling, or the BWP information may be predetermined in a protocol.
In this implementation, a bit length of the information field for FDRA may be determined through the BWP information.
Optionally, the one or more pieces of BWP information are N pieces of BWP information of N active BWPs, a bit length of the information field for FDRA corresponds to a BWP having a largest bandwidth among the N active BWPs, or, the bit length of the information field for FDRA corresponds to a total bandwidth of the N active BWPs. Or, the one or more pieces of BWP information include BWP information of an active BWP on a scheduling carrier, and BWP information of all configured BWPs on scheduled carriers, the bit length of the information field for FDRA corresponds to a BWP having a largest bandwidth among the active BWP on the scheduling carrier and all configured BWPs on the scheduled carriers, the scheduling carrier is a carrier on which the DCI is sent, and the scheduled carriers are carriers on which the channels or signals scheduled by the DCI are located.
The N active BWPs may be N active BWPs of the terminal, e.g., N active BWPs on different carriers, or N active BWPs on the same carrier.
That the bit length of the information field for FDRA corresponds to the BWP having the largest bandwidth among the N active BWPs may mean that the information field may indicate the frequency domain resource allocation of the BWP having the largest bandwidth. That the bit length of the information field for FDRA corresponds to the total bandwidth of the N active BWPs may mean that the length of the information field is determined based on the total bandwidth of the N active BWPs, such as the quantity of RBs of the total bandwidth.
Optionally, in case that the bit length of the information field for FDRA corresponds to the BWP having the largest bandwidth among the N active BWPs, all bits of the information field for FDRA are used for indicating FDRA of a first active BWP, and M2 LSBs of the information field for FDRA are used for indicating FDRA of a second active BWP, where the first active BWP is a BWP having the largest bandwidth among the N active BWPs, the second active BWP is a BWP having a bandwidth different from the first active BWP among the N active BWPs, where M2 is an integer greater than or equal to 1.
The M2 may be determined based on the bandwidth of the second active BWP.
For example, the terminal regards the maximum FDRA field length determined from N active BWPs on N carriers scheduled by the DCI as the length of the FDRA field, and each state information bit indicates the frequency domain resource allocation information of the N BWPs. For example, if N=2, an active BWP configured on the CC#1 includes Q=100 RBs, and an active BWP configured on the CC#2 includes P=50 RBs, then the FDRA indication field in the scheduling DCI is determined based on the active BWP on the CC#1. The terminal determines the time domain resource allocation information of a corresponding carrier in accordance with M LSB bits determined by FDRA, where M is determined by a size of the active BWP on the corresponding carrier.
Optionally, in case that the bit length of the information field for FDRA corresponds to the total bandwidth of the N active BWPs, the information field for FDRA indicates FDRAs of the N active BWPs jointly.
The "jointly indicating" may refer to that the FDRA indicated by the information field for FDRA simultaneously include FDRAs of the N active BWPs. For example, the N active BWPs are treated as a large virtual BWP, and the information field is used for frequency domain resource allocation in the virtual BWP. For example, as shown in Fig. 3, the active BWP on the CC#1 includes upper 100 RBs of the virtual BWP, and the active BWP on the CC#2 includes lower 50 RBs of the virtual BWP, so when RBs indicated by the information field include these two parts of RBs, scheduled RBs in the active BWP on the CC#1 and the active BWP on the CC#2 can be determined. For example, that the resource allocation indicated by the FDRA field is RB#50 to RB#130 means that resources occupied by data transmission in the active BWP on the CC#1 are RB#50 to RB#100, and resources occupied by data transmission in the active BWP on the CC#2 are RB#1 to RB#30.
The overhead of DCI may be saved though jointly indicating the FDRAs of the N active BWPs.
In an optional implementation, the scheduling method further includes: performing, by the terminal, transmission of the N channels or N signals in accordance with the DCI.
The transmission of the N channels or N signals in accordance with the DCI may be sending or reception of the N channels or N signals in accordance with the DCI.
In the embodiments of the present disclosure, the terminal receives the DCI sent by a network-side device, where the DCI is used for scheduling transmission of N channels or N signals of the terminal, the N channels include N uplink channels or N downlink channels, the N signals include N uplink signals or N downlink signals, where N is an integer greater than 1.

It should be appreciated that, as the embodiment of the network-side device corresponds to the above-mentioned embodiment shown in Fig. 2, for the specific implementation thereof, references may be made to the relevant description of the embodiment shown in Fig. 2, and the same technical effects may be achieved. To avoid repetition, the same part and beneficial effects of this method embodiment are not described in detail again.
The scheduling method provided by the embodiment of the present disclosure is illustrated below by taking a case where the network-side device is a base station as an example.

Embodiment 1

In the embodiment, it is presumed that the network-side schedules data transmission on N carriers through one DCI transmitted on a scheduling carrier.
In the embodiment, it is presumed that N=2, the base station configures for the terminal different TDRA tables on two CCs, namely CC#1 and CC#2, and the TDRA tables of the CC#1 and the CC#2 have the same quantity of rows, such as 16 rows, then the TDRA indication field carried in the DCI includes log2(16)=4 bits of information. Data channel time domain resource allocation configurations carried by the two TDRA tables may be different. After receiving the scheduling DCI, the terminal determines the time domain resource allocation of the data channels on the CC#1 and the CC#2 in the following manner.
The terminal determines, in accordance with the received TDRA indication field, an index of table entry used by data channel transmission. For data transmission on the CC#1, the index indicates a TDRA table corresponding to the CC#1. For data transmission on the CC#2, the index indicates a TDRA table corresponding to CC#2. For example, 0000 indicates that the allocation of the time domain resource occupied by the data channel on the CC#1 is determined by information corresponding to a first row of the TDRA table corresponding to the CC#1, and indicates that the allocation of the time domain resource occupied by the data channel on the CC#2 is determined by information corresponding to a first row of the TDRA table corresponding to the CC#2; 0001 indicates that the allocation of the time domain resource occupied by the data channel on the CC#1 is determined by information corresponding to a second row of the TDRA table corresponding to the CC#1, and indicates that the allocation of the time domain resource occupied by the data channel on the CC#2 is determined by information corresponding to a second row of the TDRA table corresponding to the CC#2; 0010 indicates that the allocation of the time domain resource occupied by the data channel on the CC#1 is determined by information corresponding to a third row of the TDRA table corresponding to the CC#1, and indicates that the allocation of the time domain resource occupied by the data channel on the CC#2 is determined by information corresponding to a third row of the TDRA table corresponding to the CC#2; and so on.
Further, when different CCs have different subcarrier spacings (SCSs), the terminal does not expect that the time domain resource allocation information indicated by the TDRA tables indicated by the DCI would cause a starting position of the data channel transmission to be earlier than a transmission time of the DCI.

Embodiment 2

In the embodiment, it is presumed that the network-side schedules data transmission on N carriers through one DCI transmitted on a scheduling carrier.
In the embodiment, it is presumed that N=2, the base station configures for the terminal different TDRA tables on two CCs, namely CC#1 and CC#2, and the TDRA tables corresponding to the CC#1 and the CC#2 respectively have different quantities of rows. For example, the TDRA table corresponding to the CC#1 has 32 rows, and the TDRA table corresponding to the CC#2 has 16 rows. The quantity of bits of the TDRA indication field carried in the DCI is determined by a maximum quantity of rows in the configuration tables, i.e., log2(32)=5 bits. A data channel time domain resource allocation configuration carried by each row in the two TDRA tables may be different. After receiving the scheduling DCI, the terminal determines the time domain resource allocation of the data channels on the CC#1 and the CC#2 in the following manner.
The terminal determines, in accordance with the received TDRA indication field, an index of table entry used by data channel transmission. Specifically, log2 (entry number) LSBs in the TDRA indication field are used for indicating the entry index in each table. For data transmission on the CC#1, the index indicates that a TDRA table corresponding to the CC#1 is notified by using 5 bits. For data transmission on the CC#2, the index indicates that a TDRA table corresponding to CC#2 is notified by using 4 LSBs. For example, 11111 indicates that the allocation of the time domain resource occupied by the data channel on the CC#1 is determined by information corresponding to a 32nd row of the TDRA Table corresponding to the CC#1, and indicates that the allocation of the time domain resource occupied by the data channel on the CC#2 is determined by information corresponding to a 16th row of the TDRA Table corresponding to the CC#2. For another example, that the TDRA indication field in DCI is 00001 means that the allocation of the time domain resource occupied by the data channel on the CC#1 is determined by information corresponding to a second row of the TDRA table corresponding to the CC#1, and the allocation of the time domain resource occupied by the data channel on the CC#2 is determined by information corresponding to a second row of the TDRA table corresponding to the CC#2. The above description is also applicable to other information states, and thus will not be particularly defined herein.
When different CCs have different SCSs, the terminal does not expect that the time domain resource allocation information indicated by the TDRA tables indicated by the DCI would cause a starting position of the data channel transmission to be earlier than a transmission time of the DCI.

Embodiment 3

In the embodiment, it is presumed that the network-side schedules data transmission on N carriers through one DCI transmitted on a scheduling carrier.
In the embodiment, it is presumed that N=2, the quantity of bits of the TDRA field in the DCI is determined by the total quantity of bits of the N TDRA tables. It is presumed that the base station configures for the terminal different TDRA tables on two CCs, namely CC#1 and CC#2, and the TDRA tables corresponding to the CC#1 and the CC#2 have different quantities of rows. For example, the TDRA table corresponding to the CC#1 has 32 rows, and the TDRA table corresponding to the CC#2 has 16 rows, so the quantity of bits of the TDRA indication field carried in the DCI is log2(32)+ log2(16)=9 bits. After receiving the scheduling DCI, the terminal determines the time domain resource allocation of the data channels on the CC#1 and the CC#2 in the following manner.
The terminal determines, in accordance with the received TDRA indication field, an index of table entry used by data channel transmission. Specifically, log2(32)=5 MSBs in the TDRA indication field are used for indicating an entry index in the TDRA table corresponding to the CC#1, and log2(16)=4 LSBs in the TDRA indication field are used for indicating an entry index in the TDRA table corresponding to the CC#2.
When different CCs have different SCSs, the terminal does not expect that the time domain resource allocation information indicated by the TDRA tables indicated by the DCI would cause a starting position of the data channel transmission to be earlier than a transmission time of the DCI.

Embodiment 4

In the embodiment, it is presumed that the network-side schedules data transmission on N carriers through one DCI transmitted on a scheduling carrier.
In the embodiment, it is presumed that N=2, the base station configures for the terminal a same TDRA table on two CCs, the quantity of bits of the TDRA field in the DCI is determined by the quantity of rows of the TDRA table.
Each row in the common TDRA table includes time-domain resource allocation information of data transmission on multiple CCs, such as a mapping type of the data channel, a gap between the data channel and PDCCH, and a starting symbol position of the data channel in a slot, the quantity of occupied consecutive symbols, repetition information. A simple example may be as shown in Table 1, which will not be particularly defined herein.
It is presumed that the common TDRA table has 16 rows, the TDRA indication field in the DCI includes 4 bits of information, and indicates one row of the table. For example, state information 0000 indicates that the data transmission on CC#1 and CC#2 is determined in accordance with the first row of the TDRA table. The time domain resource occupied by data scheduled on the CC#1 is determined by information related to the CC#1 in the first row of the TDRA table, and the time domain resource occupied by data scheduled on the CC#2 is determined by information related to CC#2 in the first row of the TDRA table, and so on.
When different CCs have different SCSs, the terminal does not expect that the time domain resource allocation information indicated by the TDRA table indicated by the DCI would cause a starting position of the data channel transmission to be earlier than a transmission time of the DCI.

Embodiment 5

In the embodiment, for frequency domain resource allocation, the terminal receives BWP information configured by the network side through RRC signaling, and receives one DCI including multiple pieces of frequency domain resource allocation information transmitted on the scheduling carrier, and performs sending and reception of a data channel on the corresponding carrier. The specific process is as follows.
The terminal determines a length of a FDRA field in accordance with a BWP having a largest bandwidth among N active BWPs, and each state information bit indicates frequency domain resource allocation information on the N BWPs. For example, if N=2, an active BWP configured on CC#1 has Q=100 RBs, an active BWP configured on CC#2 has P=50 RBs, then the FDRA indication field in the scheduling DCI is determined in accordance with the active BWP on the CC#1. The terminal determines the time domain resource allocation information on the carrier based on M LSBs determined according to FDRA on the corresponding carrier.
Alternatively, the terminal determines the length of the FDRA field in accordance with the total quantity of RBs included in active BWPs on N CCs, and jointly indicates the allocation of data transmission resources on the multiple CCs.
Alternatively, the terminal determines the length of the FDRA field in accordance with a BWP having a largest bandwidth among an active BWP on a scheduling carrier and all configured BWPs on scheduled carriers, so as to avoid the occurrence of different DCI payload sizes during switching among the scheduled carriers.

Embodiment 6

In the embodiment, it is presumed that the network-side schedules data transmission on N carriers through one DCI transmitted on a scheduling carrier.
In the embodiment, it is presumed that N=2, the base station configures for the terminal active BWPs having different bandwidths on two CCs. The quantity of bits in a FDRA indication field carried in the DCI is determined by a BWP having a largest bandwidth among the active BWPs on the two CCs. To be specific, if an active BWP configured on CC#1 has Q=100 RBs, and an active BWP configured on CC#2 has P=50 RBs, then the FDRA indication field in the scheduling DCI is determined in accordance with the active BWP on the CC#1. After receiving the scheduling DCI, the terminal determines frequency domain resource allocation of data channels on the CC#1 and the CC#2 in the following manner.
The terminal determines time domain resource allocation information of the carrier in accordance with M LSBs determined by FDRA. For data transmission on the CC#1, M is determined by a bandwidth occupied by the active BWP on the CC#1; for data transmission on the CC#2, M is determined by a bandwidth occupied by the active BWP on the CC#2.

Embodiment 7

In the embodiment, it is presumed that the network-side schedules data transmission on N carriers through one DCI transmitted on a scheduling carrier.
In the embodiment, it is presumed that N=2, and active BWPs configured by the base station for the terminal have a same bandwidth or different bandwidths on two CCs. The quantity of bits in a FDRA indication field carried in the DCI is determined by a total quantity of RBs in the active BWPs on the two CCs. To be specific, if an active BWP configured on CC#1 has Q=100 RBs, and an active BWP configured on CC#2 has P=50 RBs, then the FDRA indication field in the scheduling DCI is determined in accordance with 150+50=200 RBs. After receiving the scheduling DCI, the terminal determines frequency domain resource allocation of data channels on the CC#1 and the CC#2 in the following manner.
Two active BWPs on the CC#1 and the CC#2 are cascaded into a large virtual BWP at the terminal and the base station side, and frequency domain resource allocation is performed in the virtual BWP, i.e., frequency domain resource allocation information indicated by the FDRA field in the DCI is directed to the allocation within the virtual BWP. First 100 RBs in the virtual BWP represent a bandwidth that can be occupied by the data channel on the CC#1, and last 50 RBs in the virtual BWP represent a bandwidth that can be occupied by the data channel on the CC#2, as shown specifically in Fig. 3.
Specifically, an FDRA manner adopted by the DCI may be type0, type1 or type0&type1, which is not particularly limited in the embodiments of the present disclosure. If Type0 resource allocation (RA) is adopted, a bitmap of the information field is determined by a bandwidth of the virtual BWP (150 RBs) and a resource block group (RBG) size, which can realize inconsecutive resource allocation. If Type1 RA is adopted, the bit length of the FDRA field is determined by the bandwidth of the virtual BWP (150 RBs). For example, that the resource allocation indicated by the FDRA field is RB#50 to RB#130 means that resources occupied by data transmission in the active BWP on the CC#1 are RB#50 to RB#100, and resources occupied by data transmission in the active BWP on the CC#2 are RB#1 to RB#30.
As described in embodiments 6 and 7, the terminal may determine the length of the FDRA field in accordance with the BWP having the largest bandwidth among the active BWP on the scheduling carrier and all the configured BWPs on the scheduled carrier, so as to avoid the occurrence of different DCI payload sizes during switching among the scheduled carriers. For example, CC#1 is the scheduling carrier, and the bandwidth of the active BWP on the CC#1 has 50 RBs. CC#2 is the scheduled carrier, two BWPs, i.e., BWP#1 and BWP#2, are configured on the CC#2, and bandwidths of the BWP#1 and the BWP#2 are 100 RBs and 50 RBs respectively, where the BWP#2 is the active BWP on the CC#2. At this time, FDRA may be determined by a largest bandwidth (i.e., 100 RBs) among the bandwidth (i.e., 50 RBs) of the active BWP on the CC#1 and bandwidths of BWPs configured on the CC#2.
It should be appreciated that, the above-mentioned embodiments are described by only taking channel or signal scheduling on different CCs as an example, and may also be applied to multiple data channel scheduling on the same CC, which will not be particularly described in detail again.
In the embodiment of the present disclosure, the network-side device and the terminal may determine the bit lengths of multiple information fields in the scheduling DCI in accordance with multiple sets of high-layer signaling configurations for different data transmissions, and perform the data transmissions in accordance with the information fields in the single scheduling DCI. Since multiple data transmissions are scheduled through a single DCI, DCI overhead can be effectively reduced and introduction of excessive DCI payload size can be avoided.
